Summary
Neonatal cervical lymphadenitis, a rare condition, was observed in a preterm infant with Staphylococcus aureus infection. Prompt antibiotic treatment led to a favorable clinical outcome, highlighting the importance of early diagnosis and intervention.
Area of Science:
- Pediatrics
- Infectious Diseases
- Neonatology
Background:
- Cervical acute lymphadenitis is infrequently documented in neonates.
- Neonatal infections require prompt recognition and management due to potential severity.
Purpose of the Study:
- To report a case of cervical acute lymphadenitis in a neonate.
- To describe the diagnostic approach and treatment of this rare condition.
Main Methods:
- Case presentation of a 12-day-old preterm infant with submandibular swelling.
- Laboratory investigations including C-reactive protein and procalcitonin.
- Ultrasound-guided drainage and microbiological culture.
- Antibiotic therapy targeting identified pathogen.
Main Results:
- The infant presented with a tender, erythematous submandibular swelling.
- Laboratory results indicated neutrophilia and elevated inflammatory markers.
- Ultrasound revealed cellulitis, adenitis, and an abscess.
- Methicillin-sensitive Staphylococcus aureus was identified from drainage cultures.
Conclusions:
- Early diagnosis and appropriate antibiotic treatment are crucial for managing neonatal cervical lymphadenitis.
- Methicillin-sensitive Staphylococcus aureus can cause cervical lymphadenitis in neonates.
- Successful treatment resulted in a good clinical outcome for the infant.

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

171
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
